Here's something nice that the new forum has over ezBoards:
When a topic gets moved from one forum to another (such as when it's archived) the URL doesn't change. Each topic has its own number (right now you're reading topic number 1020), and that's what comprises the URL. At ezBoards, the forum ID was part of the URL, so when a thread was linked to, and then moved to an archive forum, the link would end up out of date. That won't happen here.
